I recently had my 3.73s installed by a local speed shop and now when I hit WOT the needle on the tach revs all the way up to redline and hits the rev limiter before its able to shift into the next gear. If anyone has any advice as to what maybe causing this your in put is greatly appreciated. Car is an A4 and my current mods are stated below in my sig.. Thanks... Jeff..

 

You got gears but no tune for them?

 

they reprogrammed the speedo and calibrated for the gears. They told me it has something to do with the computer. Do you think if I take it to pcmforless Bryan would be able to fix it??

 

Yeah, if you check the pcmforless site, updating the pcm for gear changes is mentioned as one of the things they do. I'd shoot him an email.

 

Yea get a tune for your car, or buy a Hypertech. Tune would be more cheaper route to go though.
